FDR Readout
View our 3 easy steps to get started
Step 1 – Getting to know you and your aircraft
During this stage, we evaluate your fleet details and local regulatory requirements. This data gathering stage may include requests for:
- FDR raw data (files downloaded from your FDR)
- Part number of FDR and acquisition unit (i.e. – DFDAU, FDIMU hardware and software part numbers)
- Configuration specific information (i.e. – HUD installed, #3 VHF radio active or inactive, etc.)
- FDR dataframe spec (in the event you have a hybrid or customized FDR recording dataframe)
- Your regulatory compliance category (i.e. – 22, 32, 57 or 88 parameter requirement)
No parameter escapes interrogation!
That is because, not only do we analyze FDR parameters, but we also teach it!
Each FDR readout may be the last FDR readout, before a serious event, incident, or accident occurs. The signature on an FDR report is a very serious matter, and we tend not to negotiate in this area. To ensure you comply with the regulation, we apply more than a mouthful of analysis techniques:
- Range check
- Sampling verification
- Resolution analysis
- Accuracy validation
- Correlational analysis
- Calibrational analysis
- Comparative analysis
- Calculative analysis
- Aeronautical & Geographical analysis
- Flight Operations analysis
FDR education is the key to compliance. Did You Know?
- Some regulators mandate the analysis of both mandatory and non-mandatory FDR parameters, with a stipulation to repair the non-mandatory parameters on the next heavy maintenance visit.
- Just because an FDR parameter falls within the required regulatory range doesn’t mean the parameter is functioning properly.
- Your AMM ATA 31-31 parameter system test octal range is often not equivalent to the accuracy limits imposed by the regulation.
- The accelerometer parameter readings are not visible to the flight crew. The only opportunity to capture a defect in vertical, longitudinal, or lateral acceleration is during the FDR readout!
